  • Publication number: 20160230108
    Abstract: Systems and methods for producing engineered fuels from solid waste material are described herein. In some embodiments, a method includes receiving a waste stream at a multi-material processing platform and separating the waste stream to remove non-processable waste and marketable recyclables. The method further includes conveying processable materials to a material classification system and incorporating additives to produce an engineered fuel from the constituents of the waste stream.

  • Publication number: 20160108328
    Abstract: Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, methods of making the fuel feed stocks, methods of producing energy from the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles and contain a sorbent. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels. In addition, one or more sorbents can be added to the feed stocks in order to reduce the amount of a variety of pollutants present in traditional fuel and feed stocks, including, but not limited, sulfur and chlorine. Further, these feed stocks with added sorbent can mitigate corrosion, improve fuel conversion, extend power generating plant lifetime, reduce ash slagging, and reduced operating temperature.

  • Publication number: 20150135583
    Abstract: Systems and methods for producing engineered fuels from municipal solid waste material are described herein. In some embodiments, a method includes combining a first waste stream that includes at least one of hard plastic, soft plastic and mixed plastic with a sorbent and increasing the temperature of the combined first waste stream and sorbent to a temperature of at least about 200° C. The method further includes combining the thermally treated first waste stream and sorbent with a second waste stream that includes fiber, and compressing the combined first waste stream, sorbent, and second waste stream to form a densified engineered fuel feedstock.

  • Patent number: 8746599
    Abstract: Systems and methods for processing and sorting a municipal solid waste stream are described herein. A system can include a processing sub-system configured to receive a municipal solid waste stream and to remove the non-processable waste, a processing apparatus configured and disposed to receive constituents of the municipal solid waste stream from the processing sub-system and reduce the size of the constituents of the waste stream to an average particle size of less than about ¾ inch, and separators configured to sort the waste stream into constituents based on density.
